: WINDOW-SASH. I

To all whom it may amw e I "Be itknown thatwe, Josnr a RAUwALD- Sr.', and FRANK RAUWA'LD, citizens of the; United States, and residents of Milwaukee,

inthe county of Milwaukee and Stateof Wlsconsm, have" invented new and useful Improvements in Window-Sashes, of which "the following'isa description, reference being had to the accompanying drawings, which are a part of this's'pecificationi i Thisinvention relates to improvements window'sash and more particularly to the? means for "securing the panes of glass in the sa.

Window sashes as now ordinarily manufactured are rabbeted or grooved on"one side toreceive the glass which is held in p'ositionby painters .three cornered tacks and putty, the tacks. serving to hold the glass in position while the putty sets or be comes sufliciently hard to'firm'ly ho'ldithe' glass in place. The putty is applied with'a putty knife and pressed into the corner space and forms a strip of putty of triangular shape in cross section, the lower face of which adheres, to the sash bar and-side face adheres to the glass. As the surfaces of both the glass and the sash bar are perfectly smooth the adherent quality of the putty is depended upon to hold the putty on the glass and'bar. Ofttimes the putty in hardenin does not properly adhere to the parts and reaks away inplaces. This breaking away presents an unsightly appearance and the glass loosens and in the course oftlme -will fall out unless putty is, again applied to the parts. I I

It is one of the objects of the presentinvention to overcome the before mentioned objectionable features and provide a window .sash with means for causing. the putty. to firmly adhere and be bound to the sash in such a manner as to anchor the putty to the sash.

A further object of the invention is to provide a window sash having lines of in v 'dentations adjacent to and under the glass into which the potty embeds when in a soft state. I I I I A further/object of the invention 1s to ,provide a window sash which is ofs mpl'e 1 construction, is strong and durable and does not addmateriallyto the cost of manufacture of thesash.

the invention consists of the improved window sash and its'parts and combinations as setforth in the claims, and all equivalents thereof.

In the accompanying drawing in which the same reference characters indicate the same parts in all of the views:

I Figure 1' is a fragmentary side view of a WIIIdOW sash made in accordance with the improved construction;

Fig. 2 1s a transverse sectional viewthereof taken'on line 22 of Fig.1; 1 V Fig. 3 is an inner edgeviewof a portion of the sash;

f! Fig. 4 is a transverse sectional view of a imodified form of sash; and I Fig.5 is an inner-edge view thereof; a r j Referring'toithe drawing the numeral 8 "indicates "a "window sash Of'rectanguIar shape which i s formed of vertical and trans versefsashbarsil and 10 connected together at" their end portions.

The bars on their inner edges are rabbeted to form the shoulders 11 and the glass grooves 12 for holding the pane of glass 13. The edge portions of the glass fit in the groove 12 and rest against the shoulders 11,.an'd a line of putty. or like material '14 while in a soft workable state is forced into the groove and againstthe side edge portion of the glass and against the inner surface of the grooved portionpf the sash bar. The exposed face 15 of the putty is beveled off from the glass to the frame edge and forms a strip of putty of triangular shape in cross section. While in frames of ordinary construction the putty merely adheres to the sash it is the essential feature of thisinvention to provide in addition to the adherence a means for anchoring the putty to the sash frame. This is accomplished by forming lines of indentations or recesses 16 and 16" in the inner face of the rabbeted portion of the sash.

- Some ofthese indentations in .the sash extend in part beneath the edge portion of the glass and others extend alongside of the side edge portions of the glass so that when the vform of projecting anchors [17 and 17 they will enter the indentations and when the putty becomes hard, firin'lyanchor the putty to the sash. The anchors 17 will extend. in partbeneath the edge of the glass and be locked thereto. 1

' In the modified formshown in Figs. 4.- and the putty is forced into the groove portions I only two lines of indentations are formed into which the putty extends for the putty.
